Question 1

What is the power source for these speakers?  Batteries, AC adapter, USB port?

Accepted Answer

the ac plug comes right from the subwoofer and there is no adapter; so it must all be built into the sub. btw, excellent choice.
with their own power source, you can use these with most any device, even a tablet, as long as it has a usb port.

Question 2

how are the speakers powered, ac wall plug or battery?

Accepted Answer

The Logitech X-140 Speakers have an AC wall plug for power, to produce greater volume, than just direct plug-in speakers.  The volume, sound quality, and frequency response is very good, for the price.  A great improvement for notebook speakers, or also a desktop PC.

Question 3

do they plug into an outlet for power?   Each one or one plug for both?   how do I connect to my computer?

Accepted Answer

Yes they do plug into the wall for power. There is one power cord and then a generous length of cord between the speakers and then there is a speaker audio cable that plugs into the back or front of your computer(or cell phone, tablet, cd player, etc) I am very satisfied with mine the have good range and volume and while the speakers are a bit large there is no sub so you save a little bit of foot room and still get very nice sound for a relatively low cost.

Question 4

what are the dimensions (length and width)? thank you.

Accepted Answer

The length is 4 inches the width on the bottom 5in and on the top it is 2in

Question 5

Can you change the volume of the auxiliary output? And do the speakers stop outputting sound once the auxiliary is plugged in?

Accepted Answer

Yes they stop working when you plug the Aux in, or if you plug headphones in. They are nice sounding speakers for the money. I use them in my workshop on my work computer. And the volume button works for me, I have the computer and Windows media player volume all the way up and adjust everything from the speakers themselves.

Question 6

what is the power consumption?

Accepted Answer

The 5 watts is the output. Simply guessing, perhaps 25 watts
consumption. The power consumption is simply not listed by the
manufacturer.

Question 7

Have a AS501 Dell Monitor and need to add sound.  Will these speakers  work with this monitor?  What other accessories or equipment do I need to make them work?

Accepted Answer

I am not familiar with the connections on the AS501 Dell Monitor, but speakers are normally designed to plug into either a sound card on the computer, or the sound output on the motherboard if it has a sound chip.  These are good sounding speakers, but I doubt you can plug them into a monitor.  Suggest you check the back of your computer and see if you have a sound output plug-in.
